C# attributes

[Fernando Serboncini]

I'm trying to revive Unity support for Haxe. The HEAD CS generator is pretty good at using C# dlls, so thanks for that! 

One issue I'm having is: how to do C# attributes in Haxe? I.e., like [Range(-100, 100)] or [ExecuteInEditMode]?

Thanks,

Fernando

Hey!

You can do that using the `@:meta` metadata. For example: @:meta(UnityEngine.Range(-100, 100)). For more complex cases you could also use string constant for that metadata, like @:meta("global::WhateverNameSpace.MyAttribute(...)")

You can also use strict metadata by using the `@:strict` meta. There is still not much documentatn about it, but you can see the unit tests (e.g.) https://github.com/HaxeFoundation/haxe/blob/development/tests/unit/src/unit/TestCSharp.hx#L693 for examples on how to use them

On a related note, is there a way to globally replace "trace" ?

I know one can do haxe.Log.trace = function(v, ?posInfo) {...}, but is there a way to do this that would work on Unity? I.e., where I don't have a main entry point and don't want to do this before every use?

You can use `static function __init__()` to initialize functions like these
